“People try to do all sorts of clever and difficult things to improve life instead of doing the simplest, easiest thing—refusing to participate in activities that make life bad.” 

- Tolstoy 


Good habits have a price. Bad habits have a cost. Either way, you pay


“What an astonishing thing a book is… one glance at it & you’re inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly & silently inside your head, directly to you.

Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. #Books break the shackles of time. A book is proof that humans are capable of working magic.”

- Carl Sagan


French philosopher Voltaire once said: “It’s difficult to free fools from the chains they revere.”

But for the 21st century, upgrade that to: “It’s impossible to free low-IQ imbeciles from their erroneous beliefs.”


“Above all, do not lose your desire to walk. Every day I walk myself into a state of well-being and walk away from every illness. I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it." - Søren Kierkegaard 


"One of the most important of the Irregular Rules, find smart people, because if you can do that, you can forget a lot of the other rules." Adam Smith, The Money Game 1968

“There are things that can be measured.  There are things that are worth measuring.  But what can be measured is not always what is worth measuring;  what gets measured may have no relationship to what we really want to know.  

The costs of measuring may be greater than the benefits.  The things that get measured may draw effort away from the things we really care about.  And measurement may provide us with distorted knowledge—knowledge that seems solid but is actually deceptive.”

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.  – Daniel J. Boorstin


“The best way to predict the future is to create it.” – Peter F. Drucker


Reinventing the wheel is bad not only because it wastes time, but because reinvented wheels are often square. There is an almost irresistible temptation to economize on reinvention time by taking a shortcut to a crude and poorly-thought-out version, which in the long run often turns out to be false economy.    -- Henry Spencer


The best dividends on the labor invested have invariably come from seeking more knowledge rather than more power. - Wilbur Wright


 The enemy of efficiency

“You’re efficient when you do something with minimum waste

            And you’re effective when you’re doing the right something.”


 “Size expectations to resources and you will rarely be disappointed.”  Living in reality is a key to happiness. Delay gratification, have a buffer, and invest for the future. What could be simpler?  “Common sense isn’t.” 


The cost of recording knowledge is small compared to the cost of acquiring that knowledge. 


There are decades when nothing happens, and there are weeks when decades happen. - Lenin

Your level of success will rarely exceed your level of personal development, 

because success is something you attract by the person you become 

– Hal Elrod 


“The best yardstick for success isn’t whether you beat a benchmark or your neighbor,” writes Adam Grossman.

 “Instead, the best measure is whether you meet your goals—while sleeping at night 

Growth is a function of the available energy. 

As energy sources have increased, the production of wealth has increased. Greater wealth meant better standard of living for ever greater number of people.

Humanity’s future is open-ended.

Why hasn’t evolution made every species freaking huge?

Aaron Clauset of the Santa Fe Institute and Doug Erwin of the Museum of Natural History, explained why in a paper that is  dense but summed up in a wonderful sentence: 

The tendency for evolution to create larger species is counterbalanced by the tendency of extinction to kill” off larger species

To Learn

To learn is to broaden, to experience more, to snatch new aspects of life for yourself. To refuse to learn or to be relieved at not having to learn is to commit a form of suicide; in the long run, a more meaningful type of suicide than the mere ending of physical life. 

Knowledge is not only power; it is happiness, and being taught is the intellectual analog of being loved.
